The present invention. rel ates. to improve-'- ments. in surface-treating machines for plans ingrwooden blocks employed incutting machines,t such as :forz instance leather cutting machines, also-:vforitreatingbutcher blocks,

and :the like.

The mainobject of the invention-is to provide a surface :treatingunachine of the "type be conveniently:adjustedrtoward and-from the surface; treating member, whereby the I depth of I the cut 'or the pressure 1 of: the surface z'treati-ng member. may :be controlled at will; 3

Another object ,:of the invention is to provide a; machine. of "the type mentioned. in

which .both work-support and the t-oolsup portware shiftable in a pluralityof directions, thereby permitting sthe surface (treating'member tobe conveniently brought over the entire;surface of thework to be treated. A further object .ofthe invention is to produce ;aimachi-ne of the character described which is simplewin construction-,.-eflicient in 7 operation, durable in use. and capable of manufacture onc-acommercialLscale, or in otherrwords one which is not so -diificult to make as to berbeyondth'e reasonable costof such a 'machineul which :will more fully iappear as-the' nature of the invention is better.understood; thesame CODSlStS: in 11 the comb nation, arrangement and I construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention. I v

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure -1 is a front elevation of a surface tool-support carriage; and Fig. 5 is a front elevation of the detailshownin Fig. 4.

Referring now to the. drawings, the numeral 10 indicates two side members of the With these and other objects view plan view thereof; Fig. 3-is a side elevation tszasaa machine frame, K zunitedl I by; thetie-ro'ds' 11,- 1 the latter extending longitudinally: of-the wmachin'e; o each' of thewsaid frames is cen- :1, trally attached. a Vertically'e'xtending screw-.1

In the a} said jtwou mentionedyuvherein 113118 work-support -ma-yl locks are also rotatably j ournaled a spindle 15 anda shaft 16, the'saidspindle and shaftv extending in parallel relation .to-the-guide.

wormgear is rotatably'mountedon its-respective blockand is provided with: ais'crewa;

in the case illustrated, it is provided. witha square end-.19, -for engagementwith a crank: handle. The spindle 15.:is provideduwith two screw-threaded portions 20' and.2l,..the. threads: of which runinopposite directions Figs. .1. and 2) :With' these threads mesh:

stance, with a square end 26, for engagement 7 With the work support co-operates a cutting tool 28 of any suitable construction, the same being mounted upon the armature shaft of an electric motor 29, carried by a support 30. This support is slidably arranged upon a carriage, including two horithreads of which mesh with those of a screwframe members 10. threaded spindles 39 is provided with an threaded spindle 35, journaled in bearing members 36 on the blocks 32. The spindle 35 is provided with a hand wheel 37, for turning the same. Each of the blocks 32 is provided with a screw-threaded bore 38, meshing with the threads of a screw-threaded spindle 39. The spindles 89 extend transversely of the machine. frame, they being journaled in bearing members thereon. To each spindle 39 is fixed an oblique toothed gear 40, meshing with a similar gear 41 on a shaft 42, the latter extending longitudinally of the machine frame and being journaled in bearing members 48' on the side One of the screwoperating handle 44. p

In using the machine,the operator places the wooden block -25 upon the work-support, and then turns the spindle 15 to bring the clamps 24 into engagement with opposite sides of the block, so as to fix the same in position on the work-support. The shaftltS is then turned in the proper direction to raise the block 25 within the reach of the cutting edges of the tool 28. lVhen the motor is then started, the upper surface of the said wooden block is planed. If the blades do not cut deep enough the work-support must obviously be raised. If the tool is cutting too deep or acting too severely on the surface on the block, the work-support is lowered. The operator, by actuating the screw-threadedspindles 35 and 39, shifts the electric motor overthe entire surface of the wooden block, so that the said surface can be treated in its entirety. It is obvious that by rotating the screw-threaded spindle 85,

the work-support is lowerjed,.the clamping members 24 disengaged from the block, and the latter removed from the machine.

What I claim is z- A surface-treating"machine comprising a frame, a screw-threaded spindle extending vertically on each end member of said frame, a block slidable on each spindle, a worm gear rotatably mounted on each block provided with a screw-threaded bore, the threads of each bore being inmesh with the respective spindle, a horizontally extending guide member connecting said two blocks, a:

screw-threaded spindle journaled in said two. blocks extending parallel to said guide member, said last-mentioned spindle being provided with two screw-threaded portions,

the threads of which run in opposite direc-.

tions, a work-support including two elements movable on said guide member, each work-support element-being provided with.

riage movable transversely on said frame,

,a tool-support adapted to move longitudinally on said carriage, means for shifting said carriage, means for moving said toolsupport on said carriage, a shaft rotatably mounted in said b1ocks,-and a worm on each end of said shaft in engagement with the worm gear on the respective block. whereby upon rotating said shaft said work-support is raised or lowered in relation to said tool support.
